Polyamide 66/nanoclay Composites: Synthesis, Thermal And Flammability Properties

Sudesh Rathi and J. B. Dahiya

Volume 3, Issue 5, Page 381-387, Year 2012, Current Issue | DOI: 10.5185/amlett.2012.5354

Keywords: Poyamide 66; nanoclay; thermogravimetry; thermal stability; UL-94 test.

Abstract: 

PA66/nanoclay nanocomposites with flame retardant (dimelamine phosphate) and other supportive additives (ammonium pentaborate, zinc borate and potassium nitrate) were prepared by melt blending method using single screw extruder. The prepared nanocomposites were characterized by XRD and FTIR techniques. The thermal properties were analysed using thermogravimetry and differential scanning calorimetry. A significant reduction in flame spread rate in UL-94 horizontal test was observed on inclusion of ammonium pentaborate to PA66/nanoclay/dimelamine phosphate composite.  Copyright © 2012 VBRI Press.
